My nexus 7 have been fine till a few days ago until the 4.3 update rolled out, I have been using a slightly damaged charger(The chargers cable has some cuts). After the 4.3 update it seems I have had a hard time powering on the nexus 7 after its battery goes to 0%. I have been using my nexus 7 alot on gaming like 5-8hrs per day and i play mostly by charging at the same time (playing while charging).
after 4.3 came out my nexus 7 lost it root, i rooted i again. could this be a problem?
its been 3 days now my nexus 7 hasn't been charging well, it only charges upto 1% i can power it on but it power offs in a flash.
Is the battery damaged ?
Do i need to purchase a new battery?
i need some quick help pls i am missing my nexus 7 like hell now . :crying::crying:

Try a non stock charger.. Any other microusb charger may help along with some patience of letting it charge for sometime . I have been experiencing great battery life with my n7 with the latest 4.3 update.

I think your battery is problem..maybe you should try to open your tab and pull the battery cable out for about 10 min and then put the cable back.. Check for video in YouTube for how to dissamble the tab.. Hope that help you..

Make sure you are using proper 2000mA charger. I have had issues with battery in my GT-P6800 using el cheapo adapter in the car. It was advertised as 2A charger but would put out only 900mA after it got hot.
Just finished charging GT-P1000N on AC charger and plugged into USB. HumberOS CM10

If you are yoing to attemt to pull the battery be careful. Watch the video carefully and then try it. you do not want to damage any of the clips or internals.

Android system used 46% of battery! Ideas?

What's so weird about that? Your device has been on for nearly 8 hours and it's at 73% battery life. You've clearly not been using the device very much in that time, so obviously the system processes will have a higher percentage than anything else.
Exactly the same thing happened with me today. I've never had android system consuming more battery than my screen, and today the android system battery consumption stood at almost 50% (twice that of screen). The tablet was idle for around 12 hours (WiFi off) and the battery fell by around 15%. Never ever happened before.
I upgraded to 4.2 a couple of days back.

Do you use Llama or any other app like that by any chance? I'm just trying to figure out what could be the root cause of this
Sent from my Nexus 7 using xda app-developers app

tablet been on 3 hours and 36 mins done nothing with it and its already used 25% battery
Android OS is at 64%
old 16gb with 4.2 on, same time and just sitting doing nothing only used 3% battery

Haven't been able to figure out the reason unfortunately. If I do, would definitely post on here. Hope you guys would do the same.

Hi everyone,
I searched the forum for a satisfactory answer yet I don't seem to find one so I'm going to ask here...
I have the habit of plugging my Nexus 4 as soon as I get home, keep it plugged overnight, and unplug it the next day when going to work. About two weeks ago I noticed that occasionally the phone indicates that the phone is fully charged yet, some minutes afterwards it indicates that the battery is at 98-99% and is charging again. I was quite intrigued so I started using some battery applications (e.g. Battery Widget Reborn) and I now notice that the "problem" is quite frequent and happens every single time the phone is plugged (I tried withe the original USB cable that came with the phone as well as with other cables). Attached is an image showing the weird pattern that I'm having...
Does any one have the same problem ? Anyone cares to explain to me why this is happening ???

Isn't that done on purpose? You don't want to keep charging at 100% so the phone discharges after reaching 100% for a while.

When 100% is reached, the battery, for the best of my knowledge, is not used... Therefore, I find that it discharges very very quickly for an unused battery !
Mine does that as well. I thought that was normal?

It's Normal as phone batteries reach 100, discharge a bit and stays there. Btw ROM + Kernel?

Just stock Android 4.2.2
How quickly it uses that small amount of battery that kicks it back into charge mode is going to depend on what you have running and syncing in the background.

So I'm running Danvdh's GPE ROM on my S4 on 4.4.2 and in the last few days my charging has become really slow. I'm using Samsung's charger that came with the S4 but the charge seems to be trickling in and the S4's battery isn't doing so well either, 7 hours with 3 hours screen on time.
In the kernel app it shows that the charging current is 1A, which is lower than the 2.1 the Samsung charger usually outputs, you can change the charging current in this kernel app however I haven't done so, I've even reset the settings to default but still the issue persists

The battery could be going up. Sometimes when they fail they fail in a hurry. Like they go from working fine to bad overnight.
Other times they gradually decline in quality over many months.
If you have access to another battery that's always a good thing to try first.

sometime the battery bugged..try this
pulled out the battery for 30 minutes and get it back in and charge normally.
Why is there the assumption that 3 hours screen on time is not good? It's perfectly normal.
It can be 2 things.
Your charger, so try a different charger of the rom/kernel you are using.
Hi Guys,
I've seen a few people post about this error on reddit where their Nexus 10 is at anywhere from 30-60% battery and it suddenly drops to 0%, everyone reporting the problem seems to of had their tablet for a year and a half...
Why is this happening, what's the fix and is it the battery needing replacing?
Is this covered by warranty if purchased through the Google Play store?
Anyone able to help/advise?
Bad battery. I had to replace my battery and the problem went away. You will have to buy an aftermarket battery and install it.

Hi,
In my case the battery would drop from 20% to 0%, but after letting it fully discharge and then charge fully while turned off it stopped happening. Don't know why, but randomly it starts again, the same procedure always worked for me.
However in some cases it can be indeed a faulty battery and need replacement.

I contacted Google and apparently they'll fix it as the tablet is in good condition and it's still in it's 2 years warranty.
